Adds a font to the document.
The font name and a description of the font style is held within
the document. However the actual font itself is not added to the
document unless the language is Unicode. (When Unicode is
specified, this method will embed the font without subsetting.) If
you wish to embed a font or use the Unicode language, you should
use the EmbedFont method.
When a client opens the PDF Acrobat will attempt to find the
exact same font on the client system. If the exact font is not
available then a substitute font will be chosen using the font
description to determine the best match.
The following fonts are guaranteed to be available on every
Additionally you can add any TrueType, OpenType or Type 1 font
that you have installed on your system. The name you should use is
the one referenced in your fonts folder. For example.
- Arial Black
- Arial Black Italic
- Book Antiqua
- Book Antiqua Bold
- Book Antiqua Bold Italic
- Book Antiqua Italic
- Venetian301BT Bold
The AddFont function returns the Object ID of the newly added
Font Object. Typically you will want to assign this return value to
the document Font property using code of the form.
theDoc.Font = theDoc.AddFont("Courier")
If the specified font could not be found then you will get an
Object ID of zero returned. You may wish to check for this
possibility otherwise a default font will be used.
Fonts are cached so newly added fonts will not be available to
ABCpdf until the application is restarted. If you need to
dynamically load a font you can pass this method a path to your
font file. This will add the font to the cache and make it
available for use. You should not move, rename or delete a font
file which has been dynamically loaded using this technique.
Why is my language a string?
In older versions of ABCpdf the language parameter was a string.
So you might find code of this form.
In more recent releases the language parameter has been changed
to a true enumeration. This is a safer way of coding as it allows
the compiler to ensure that the values you are using are valid.
Your new code should look like this.
The names of the items in the LanguageType enumeration are the
same as the values of the strings used in previous versions. So
changing your code should be a simple search and replace operation.
If you see a language of "" this equates to LanguageType.Latin.
